To effectively use any of the user services from the ldap palette, the NiagaraAX host running a station must be installed on a network with an existing LDAP (or Active Directory) server, where support is available for LDAPv2, and if using AX-3.8 stations, either LDAPv3 or LDAPv2. When configuring the user service in the station, you will need information supplied by the administrator of that LDAP system.

In AX-3.8 stations (only), if using Kerberos authentication for either of the LDAPv3-compatible user services, information will also be needed from the Kerberos administrator (possibly the same person).
